MadeInGermany is correct, but you probably want to know why:

If you check the HTML source code you produce you will see that indeed there are three lines as Scott said and suggested. HTML source code, though, is not displayed as it is when you display it using a web browser. The browser interprets it and part of this interpretation is to "interpret away" the line breaks.

MadeInGermany just put the HTML equivalent of line breaks (the "<br />" tags) into the text, which will - when interpreted by a web browser - produce line breaks. Notice, that your text will, when showed in a web browser, look the same if you write:

Code:
Var_name="This is first line.<br />
This is second line.<br />
This is third line."

or

Code:
Var_name="This is first line.<br />This is second line.<br />This is third line."

because the "away-interpretation" of real line breaks works both ways: the browser simply ignores them and it will also ignore their absence.

I hope this helps.

bakunin

/PS: remove the (real) line breaks from your variables content, the browser would ignore them anyway. Their existence is probably the reason why your sed-statement is failing: web browsers ignore line breaks, but sed does not.

git-web--browse

GIT-WEB--BROWSE(1)						    Git Manual							GIT-WEB--BROWSE(1)

NAME

       git-web--browse - git helper script to launch a web browser

SYNOPSIS

       git web--browse [OPTIONS] URL/FILE ...

DESCRIPTION

       This script tries, as much as possible, to display the URLs and FILEs that are passed as arguments, as HTML pages in new tabs on an already
       opened web browser.

       The following browsers (or commands) are currently supported:

       o   firefox (this is the default under X Window when not using KDE)

       o   iceweasel

       o   konqueror (this is the default under KDE, see Note about konqueror below)

       o   w3m (this is the default outside graphical environments)

       o   links

       o   lynx

       o   dillo

       o   open (this is the default under Mac OS X GUI)

       o   start (this is the default under MinGW)

       Custom commands may also be specified.

OPTIONS

       -b BROWSER, --browser=BROWSER
	   Use the specified BROWSER. It must be in the list of supported browsers.

       -t BROWSER, --tool=BROWSER
	   Same as above.

       -c CONF.VAR, --config=CONF.VAR
	   CONF.VAR is looked up in the git config files. If it's set, then its value specify the browser that should be used.

CONFIGURATION VARIABLES

   CONF.VAR (from -c option) and web.browser
       The web browser can be specified using a configuration variable passed with the -c (or --config) command line option, or the web.browser
       configuration variable if the former is not used.

   browser.<tool>.path
       You can explicitly provide a full path to your preferred browser by setting the configuration variable browser.<tool>.path. For example,
       you can configure the absolute path to firefox by setting browser.firefox.path. Otherwise, git web--browse assumes the tool is available in
       PATH.

   browser.<tool>.cmd
       When the browser, specified by options or configuration variables, is not among the supported ones, then the corresponding
       browser.<tool>.cmd configuration variable will be looked up. If this variable exists then git web--browse will treat the specified tool as
       a custom command and will use a shell eval to run the command with the URLs passed as arguments.

NOTE ABOUT KONQUEROR

       When konqueror is specified by a command line option or a configuration variable, we launch kfmclient to try to open the HTML man page on
       an already opened konqueror in a new tab if possible.

       For consistency, we also try such a trick if browser.konqueror.path is set to something like A_PATH_TO/konqueror. That means we will try to
       launch A_PATH_TO/kfmclient instead.

       If you really want to use konqueror, then you can use something like the following:

	   .ft C
		   [web]
			   browser = konq

		   [browser "konq"]
			   cmd = A_PATH_TO/konqueror
	   .ft

   Note about git-config --global
       Note that these configuration variables should probably be set using the --global flag, for example like this:

	   .ft C
	   $ git config --global web.browser firefox
	   .ft

       as they are probably more user specific than repository specific. See git-config(1) for more information about this.
